1992 to 2001

Catalina and Claude, after leaving San Andreas, begin a nine year journey to Liberty City, going through many American states committing bank robberies, including Texas and New Mexico. The two, however, continue on their journey to Liberty City, reaching their destination in October 2001.

2001

After arriving in Liberty City, Catalina begins discussions with and becomes the leader of the Colombian Cartel and, with some of their members (including Miguel) rob a bank in the city. After robbing the bank she shoots Claude, leaving him for dead, and explaining that he is 'small time', ending a nine year relationship. She continues her criminal activities with the Cartel, increasing the production of SPANK and attacking the Yakuza on Staunton Island and the Leone Family on Portland. During this period, Claude managed to escape from an LCPD convoy with, unintentionally, help from the Colombian Cartel (who were seeking to capture the Old Oriental Gentleman) and began working for Leone made man and nightclub/brothel Luigi Goterelli. After proving himself, Claude begins to work for the Family Don, Salvatore Leone, who has him followLuigi's Sex Club 7 barman Curly Bob to Portland Harbor, where he is seen to sell Leone secrets to Catalina and Miguel. Salvatore then has Claude and 8-Balldestroy a freighter used by the Cartel to produce SPANK.

Claude later flees to Staunton Island and begins to work for Yakuza co-leader Asuka Kasen who begins to attack the Cartel following the death of her brother Kenji at the hands of a 'Cartel assassin', which was really Claude working on orders from Donald Love. Love later sends Claude to collect a package from a construction site in Fort Staunton, where he once again meets Catalina and Miguel, with Catalina shooting Miguel in the back and escaping empty-handed. Asuka, desperate to exact revenge for her brother's death, begins to torture Miguel for information, with Claude then using the information to attack Cartel interests, including destroying stands selling SPANK run by the Uptown Yardies.

Personality

Catalina is portrayed as a reckless and extremely aggressive psychotic woman, who even turns on close partners if they cease to be useful to her (as seen with Carl, Claude and Miguel). Some of Catalina's psyche is brought to light during her robberies with Carl Johnson, frequently shooting pedestrians, police, and anyone who gets in her way. She also seems to suffer from a Persecution Complex, possibly due to cruel treatment by her stepfather as a child, telling Carl, after he criticizes her use of extreme force, that "They had to die because YOU were slow and stupid, like a big fat brat that eats chocolates while his father gives nothing to his stepdaughter but stale bread!"

Trivia

Catalina's top and appearance is noticeably different from the original GTA III PS2 release than the later GTA III releases. In the PC version she has a lock of hair on her forehead and a ponytail. In the Xbox and IPad version, she also wears a pink tube top with the black leather jacket, green pants with her pink underwear sticking out behind her, black shoes, and has a tattoo on her lower back.

Her surname is never revealed. Although she is Cesar Vialpando's cousin, there is nothing to suggest her last name is Vialpando.

Catalina originally wore a skirt and leggings.

She is the only main antagonist in the GTA III Era to appear in more than one game.
